Over the past eight months, City staff has been working the property owners in conjunction WIth Kimley-Hom to implement the vanous publIc mfrastructure improvements. At the request of property owners and developers, Kimley-Hom performed a number of additional final design services since the Consultant Work Order was approved on August 22, 2005. A majority of these additional serVIces have been reqUIred as a result of changes in the project design and/or the need to coordmate the proposed improvements WIth the adjacent property owners/developers. Also, a number of roadway alIgnments and access points were evaluated and designed. The followmg is a general summary of these addItional services: .
